iPhone Charging issue on a Mac
I Have bought iPhone 12 Pro Max, and since it does not have a charger, I am forced to charge it via USB-to-Lightning cable on my iMac Pro. Now, when I'm charging on a macOS it is really fast, it gets from 20% to 90% in 1h and 30m but when I'm on Windows 10 Bootcamp on the same iMac Pro, with the same cable charging the same iPhone 12 Pro Max, it takes at least 3 hours to get from 20% to 90%. Why is that? Is there some configuration on Windows 10 that enables this "faster" charging since clearly it is not the hardware issue.
I'm considering purchasing MacSafe charger, but i'm reluctant since I've saw case damage that may occur. Also, if I connect that MagSafe charger to my iMac Pro via USB-type C, should I get some reasonable charging speed or not? I just don't want to purchase that Power Brick that Apple sells it separately, since here where I live it is priced more than twice than in the US?
How Can I Speed up charging on a Mac running Windows 10 in BOOTCAMP? Has anyone else have this issue?
Thx,
iPhone 12 Pro Max, iOS 14
